648368 ÷ 78 
Our goal is to divide 648368 by 78.

Advancing to step 1:
When dividing 6 by 78, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 78

On to step 2:
78 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (8) of the dividend behind the 64 and repeat the process: 648 / 78

On to step 3:
78 goes into 648 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 624 from 648 to get 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 78

Moving on to step 4:
When dividing 243 by 78, we get 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtract 234 from 243 to get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 78

Going ahead to step 5:
If we divide 96 by 78, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 831.0
If we take 78 away from 96, we end up with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 78

Advancing to step 6:
188 divided by 78 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 8312.0
The remainder is 32 after subtracting 156 from 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 7:
The number 78 fits into 320 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 8312.4
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 8:
If we divide 80 by 78, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 8312.41
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
78 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 8312.41
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 8312.4102
Deduct 156 from 200 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
If we divide 440 by 78, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 8312.41025
If we take 390 away from 440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
78 goes into 500 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 8312.410256
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
If we divide 320 by 78, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 8312.4102564
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
78 can be fit into 80 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 8312.41025641
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 8312.41025641 and a remainder of 2e-09.
